1. A method for determining a total hazard estimate of a life threatening ventricular arrhythmia, comprising the steps of:
- obtaining one or more physiological parameters of a patient from one or more sensors;
communicating the physiological parameters to a medical device processor;
wherein the medical device processor utilizes an algorithm to determine a total hazard estimate of a ventricular arrhythmia based on the one or more physiological parameters, wherein the algorithm, for each of the one or more physiological parameters of a patient, calculates an individual hazard estimate given by y1(t)=h1(t)⊗
x1(t), wherein h1(t)=k1ek2t, t is time, y1(t) is the individual hazard estimate at time t, k1 and k2 are constants for the given parameter, x1(t) is the physiological parameter at time t, and ⊗
is a convolution operator, wherein the algorithm calculates the total hazard estimate which is either a linear or nonlinear summation of individual hazard estimates, and wherein the algorithm utilizes an adaptive filter to alter each of the constants periodically;
wherein the one or more physiological parameters include at least one of sleep pattern, heart rate change during dialysis, fluid removed during dialysis session, and sodium level;
wherein the medical device processor is configured to provide an adjustment of a future dialysis prescription for the patient based on the total hazard estimate; and
wherein the medical device processor determines whether an arrhythmia is due to any one of fluid management, electrolyte management, or both fluid management and electrolyte management.
